DS3695A/DS3695AT/DS3696A Multipoint RS485/RS422 Transceivers

Check for Samples: DS3695A, DS3695AT, DS3696A

FEATURES

DESCRIPTION

The DS3695A and DS3696A are high speed

•

Meets EIA Standard RS485 for Multipoint Bus

Transmission and is Compatible with RS-422

differential TRI-STATE bus/line transceivers designed

to meet the requirements of EIA standard RS485 with

extended common mode range (+12V to −7V), for

multipoint data transmission. In addition they are

compatible with requirements of RS-422.

•

10 Ns Driver Propagation Delays (Typical)

Single +5V Supply

−7V to +12V Bus Common Mode Range

Permits ±7V Ground Difference between

Devices on the Bus

The driver and receiver outputs feature TRI-STATE

capability. The driver outputs remain in over the

entire common mode range of +12V to −7V. Bus

faults that cause excessive power dissipation within

the device trigger a thermal shutdown circuit, which

forces the driver outputs into the high impedance

state. The DS3696A provides an output pin (TS)

which reports the thermal shutdown of the device. TS

is an “open collector” pin with an internal 10 kΩ pull-

up resistor. This allows the TS outputs of several

devices to be wire OR-ed.

•

Thermal Shutdown Protection

High Impedance to Bus with Driver in TRI-

STATE or with Power Off, over the Entire

Common Mode Range Allows the Unused

Devices on the Bus to be Powered Down

•

Combined Impedance of a Driver Output and

Receiver Input is less than One RS485 Unit

Load, Allowing up to 32 Transceivers on the

Bus

Both AC and DC specifications are guaranteed over

the 0°C to 70°C temperature and 4.75V to 5.25V

supply voltage range.

•

70 mV Typical Receiver Hysteresis

Available in SOIC Packaging
